of Brooklyn, in thecounty of Kings, and in the State of' New York, have invented a certain new and useful Improvement in Looking Mechanism for Vault's, and do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to provide a locking mechanism for vaults, which has exceptional strength, which is positive in operation, which may be readily operated, and which is provided with power connections for effectively the same.

A further object of my in'venion is to provide an adjustable grill which may be moved into and out of position in front of the door opening by any one upon the interior of the vault, and which may also be operated by anyone outside of the vault, who is familiar with the combination of the lock used upon the vault.

I have shown one embodiment of my invention in the accompanying drawings, in which- Figure l is equipped with a by means of my mechanism; Fig. 2 section of the same,

an elevation of a vault door adapted to be locked is a horizontal crossshowing the door in its open position; Fig. 3 is a transverse crosssection of the portion of the wall which is provided with the combination lock and valve-operating mechanism; Fig. 4 is a transverse vertical cross-section taken at right angles to the section shown iirliig. upon the line of said figure F g. 5 is a similar transverse cross-section taken on the line 5-5 of Fig. 3; and Fig. 6 is a diagrammatic representation of the entire operating system for the locking mechanism.

In the drawings, 1 is a vault which is provided with a door 2 supported upon a my upon a Journal 4: of

tary bracket 3, pivoted the usual type. The front of the door 2 is provided with a plurality of radiating r'idS 5 designed to be operated by means of a hand-wheel 6 to engage with recesses provided in brackets 7 carried by the door cas ing, in order to bring, the door into its coin- The door 2 is also; provided with a handle 8 for opening and closing the same. Through the front of the wall 1 projectsa shaft 9 carrying a'handwheel 10 for operating the same. The shaft locking and unlocking" improved form of locking Q-carries upon its inner end adjacent to the inner surface of the wall of the vault a valve i1, having curved passages 12 and 13, designed to register with passages 14 and 15 provided in a removable block 16 inserted in the inner face of the wall of the vault. The block 16 is retained-in position in the face of the vault wall, and in its proper position in relation to the valve 11, by means of a nut 17, which engages a screw-threaded shank 18 attached to the center of said valve 11. In front of thevalve 11 the wall of the vault is provided with a circular cavity 19, the inner wall of w? T provided with a pair of electrical (-01 l "i, A retary circuit breaker the shaft 9 opposite these contacts and 21, so that a certain position of the shaft 9 the circuit is completed from one of the contacts through the circuit breaker to the other of said contacts. Immediately in front of the circuit breaker 22, the shaft 9 also carrise a slotted projection 28 with which a bolt 24 cooperates. The position of the bolt 2% is controlled 3y means of a. tumbler niechanism 25 which is operated in the case of all combination locks, hy a hand-wheel 26, the hand-wheel in this instance being carried upon a sleeve which surrounds the shaft 9.

The valve 11 eontaii g' the ports 12 and 13, is designed to conoi admission of compressed air from an air compressor to apair'of. cylinders 29 and 3D. In one position of the valve li as shown in Fig. 6, the air is conveyed from the air compressor 28 through a pipe 31 to the valve 11, whence it passes into a pipe 32, having one branch 33 leading to the inner end of the cylinder 29, and another branch 3% leading to the correspondin end of the other cylinder 30. While the valve ll is in this position,v the other passage 13 therein permits the air to be exhausted from the other ends of the cylinders 29 and. 30. Thisis effected by means of a pipe 35 leading from the outer end of the, cylinder 29, which pipeis connected with a similar pipe 36 leading from the-corresponding end of he cylinder 80, which pipes are connected through the passage 13 in the valve 11 to an exhaust pipe 37. By merely changing the position of the valve 11, it will be seen that the compressed air can be led into the outer ends of the cylinders, instead of to the inner ends, as shown in Fig 6, and that when the air isthus led the air is sim l means of wires 4+3 c I a. i 1 a 4 1 coming haniopcmlco smisoli s6, to cock as czii scd so which it *oci'mi'is o so cifi ocgyfic 6 2311c moici' gearing A tho Volvo Iii is oliHS move posi'iicn in oi: tho cylinders .oit is completed i Ii, iiioi'cisy driv- .k 21ml 3% the cl ical other out.
